ASH SIFTER.

SPECIFICATION forming part of Letters Patent No. 316,653, dated April28,1885.

Application filed January 5, 1885. (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL J. PHREANER, a citizen of the United States,and a resident of the city and county of Philadelphia, and 5 State ofPennsylvania, have invented a new and useful Improvement in Ash-Sifters,of which the following is a specification.

The object of my invention is to furnish a sifter for separating theashes from the unro, burned coal which will be perfectly dustless. Inall places where coal is used as a fuel there is a considerable wasteoccasioned by unburned pieces being raked down and falling among theashes. I 5 I propose placing my sifter in a perfectly dust-tight case.

In the accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate similar parts in the severalviews, Figure 1 is a longitudinal section through the center of mysitter; Fig. 2, a transverse section, and Fig. 3 a plan, of the Sifterwith the top removed.

A isa case or box furnished with a lid, B, at its top.

is the sieve, which is shown in the drawings as hexagonal in section;but it may have any other desired shape. The sieve is hung upon an axle,D, the ends of which are furnished with suitable bearings in the case A,and one end is furnished with a crank and handle, E, by means of whichthe sieve may be rotated.

F is a drawer in the bottom of the case A, into which the ashes fallfrom the sieve O.

The sieve is furnished with a trap or door, I, which is opened to placethe ashes within it, and the ends of the sieve at the ends of the trap Iare furnished with segmental projections H,which fit closely against theconcaves G, which, with the wings K K,which project down from the top ofA, prevent, in a great measure, the escape of dust from the box when thelid Bis opened to refill the sieve. The parts H and G shut off allescape of dust from the ends of the box and the wings K from the sides.The wings K also serve as guides for passing the ashes to the sieve.

L L are wings from the sides of case A which are to prevent the rise ofdust, and to guide the ashes into the drawer F.

The arrangement and number of the wings hereinshown and described may beconsiderably varied without altering my invention, and, as I beforestated, the sieve may have any desired and suitable cross-section.

After the ashes have been placed in the sieve the door I and lid B areclosed, and the sieve is revolved by the handle F. This causes all theloose and fine ashes to fall out into the drawer F, some fifteen ortwenty revolutions being sufficient. The unburned coal remains in thesieve, and after the ashes have been emptied from the drawer the door Imay be raised and the coal dumped directly from the sieve to the drawer.

Having thus described my invention, I claim- The herein-describedash-sifter, comprising the box A, provided with the concaves G and 7cwings K and L, the sieve G,having the door I and segmental projectionsH, and the drawer F, substantially as described.
